How we built it
When we set out to build Podstar for the hackathon, we knew we wanted to create something that could redefine podcasting. Our vision was simple: make podcast creation as easy as writing a script, while maintaining high-quality production standards. The challenge? Building a platform that could offer robust AI-powered functionality, seamless user experience, and dynamic content discoveryâall within the tight time frame of the hackathon.
Our journey began with selecting the right tech stack. We chose Next.js for its ability to handle a fast, scalable web application with server-side rendering, which was crucial for performance. TypeScript was our go-to for ensuring the platform would be reliable and maintainable long-term, giving us the peace of mind to move quickly without sacrificing code quality.
But what truly brought Podstar to life was Convex. We needed a backend solution that was powerful yet simple to work with, allowing us to focus on building the platformâs core features. Convex provided exactly that, handling all our application data and logic effortlessly. With Convex, we were able to manage complex queries, mutations, and actions with ease. From validating user inputs to error handling, Convex kept the backend running smoothly, while we concentrated on delivering a superior user experience.
One of the core aspects we focused on was user authentication, as we wanted users to easily sign up and manage their podcasts securely. Here, Clerk came into play, integrating seamlessly with Convex to provide a rock-solid authentication system. With Clerk handling login and registration, we were able to ensure that users could access their accounts securely and effortlessly.
As we dove deeper into the project, our attention shifted to the core functionality of Podstar: podcast creation. This was where OpenAI became essential. We integrated their API to enable multi-voice AI podcast generation, allowing users to upload a script and choose from a variety of AI-generated voices. It was a game-changer, transforming what could have been a daunting technical task into something as simple as a few clicks.
Next, we built out the front end. Using ShadCN and Tailwind CSS, we crafted a visually appealing, responsive design that worked flawlessly across all devices. The home page showcases trending podcasts with a sticky player that allows continuous playback as users explore the platform. The Discover Page was designed to help users find new and popular podcasts, complete with personalized recommendations.
Our Create Podcast Page is where the magic really happens. Users can generate podcasts in minutes using OpenAIâs multi-voice AI, with dynamic voices that make each podcast unique. We also implemented AI-driven image generation for podcast thumbnails, making sure creators get the full package without ever needing expensive equipment or technical skills.
Throughout the hackathon, we constantly improved Podstarâs features. From a fully functional search engine to a polished profile page where users can manage their podcasts, every element was designed with the user in mind. The podcast player itself became a key focus, offering backward/forward controls, volume adjustment, and mute/unmute options for a seamless listening experience.
The backend storage and data handling for audio files and metadata were all managed through Convex. We used its file storage capabilities to store, serve, and manage all the podcasts and generated content, ensuring smooth playback and fast access. Convex also handled our databases, where we managed user data, podcasts, and transcripts.
Looking back, building Podstar was both exhilarating and challenging. We worked tirelessly to ensure it was not just a platform for creating podcasts but a complete ecosystemâone that made content creation effortless, user engagement meaningful, and discovery exciting. Each line of code was written with the goal of empowering creators, making Podstar a platform anyone could use, whether theyâre a seasoned podcaster or just getting started.

Challenges we ran into
When we first found out about the hackathon, we were late to the game. With limited time, we had to dive headfirst into learning Convex, a platform we hadn't worked with before. Understanding its capabilities and figuring out how to integrate it into Podstar was a steep learning curve. The clock was ticking, and we had to quickly get familiar with Convexâs API, error handling, and database structure, all while building a functional app.
But that was just the beginning. As we started building, we ran into a series of unexpected bugs, from authentication issues to glitches in the AI voice generation. One challenge was ensuring the AI-generated voices felt natural, engaging, and diverse enough to suit a variety of podcast topics. We had to experiment with different configurations, and the bugs seemed relentless. There were moments when audio generation would either take too long or produce lower quality than we wanted. Balancing speed and quality became a real battle.
Then came the complexity of creating a seamless user experience. Building advanced features while keeping the interface simple was crucial, but it wasnât easy. We needed to ensure that users could create and listen to podcasts effortlessly while the platform managed the heavy technical lifting in the background. Each problem required us to pause, regroup, and often rethink our approach. However, every solved bug and technical hurdle brought us one step closer to building something truly special.
Accomplishments that we're proud of
Weâre incredibly proud to have built a platform that brings down the barriers to podcasting, making it accessible to everyone, from first-time creators to seasoned podcasters. One of our biggest accomplishments was seeing our AI voices sound natural, expressive, and engaging across diverse podcast genres. That alone felt like a major win!
Another point of pride is our ability to learn and adapt. Despite having very little time, we dove into Convex, a platform new to us, and mastered its functionalities quickly. From handling queries and mutations to working with authentication and file storage, we picked up these skills in record time and successfully integrated them into Podstar.
We also pushed ourselves to deliver a feature-rich platform on time. The journey wasnât easy, but we enjoyed every challenge, every solved bug, and every new feature we added. By the end, we had a fully functional platform that offers robust podcast creation, seamless playback, and dynamic discoveryâall completed within the hackathon timeline. Weâre proud not just of the end result but of the growth and learning we experienced along the way.
